Genes play a part in how your body balances calories and energy. Children whose parents are obese also tend to be overweight. A family history of obesity increases your chances of becoming obese by about 25 to 30 percent. Heredity does not destine you to be overweight, but by influencing the amount of body fat and fat distribution, genes can make you more susceptible to gaining weight. You cannot change your genetic makeup by willpower any more than you can make yourself taller or shorter by wishing. But you can still achieve your weight loss goals even with a family history of obesity.

Culture

People learn to eat and cook the way in which they were brought up. Food choices and combinations are learned very early in life. Social events and family rituals are often centered around large meals. Today's culture promotes eating habits that contribute to obesity. People may serve large portions and foods that are most readily available instead of choosing foods that are most nutritious. Cooking with butter, chocolate and other high-caloric foods is a normal part of the American diet. Also, food is often used as a reward in this country. Children are treated to sweets for cleaning their room, and the team is taken for pizza or ice cream after the game. Seldom is eating only when hunger is present.

Emotional or Psychological Factors

Food is often a source of solace or celebration. If we feel blue, we may turn to food. If we celebrate a new job or birthday, we may go out to a big dinner. If a friend is grieving, we bake them a pie. Often as children, parents told us to clean our plates. Food carries many significant memories from our past. Food may be your best friend. Food may become less important in your life after weight loss, especially if you have surgery. Weight loss will allow you to acquire new interests in your life and become more active and varied in your activities.

Gender

Muscle uses more energy than fat does. Men have more muscle than women, and burn 10 percent to 20 percent more calories than women do at rest. For this reason, women are more likely to be obese.

Age

As you get older, the amount of muscle in your body tends to decrease, and fat accounts for a greater percentage of your weight. This lower muscle mass leads to a decrease in metabolism. Your metabolism also slows with age. Together, these changes reduce your calorie needs. If your food intake is not adjusted, you will gain weight.

Medical Problems

Less than 2 percent of all cases of obesity can be traced to a metabolic disorder, such as low thyroid function or hormonal imbalances.
